RSA Java：私钥不能用于加密

Question

I am using RSA Algorithm for encryption and decryption of files. Currently, I have implemented the code on my local machine (Windows) and used private key to encrypt the file and public key to decrypt the same and it worked fine.

However, when I deployed my application to AIX machine than same approach thrown an exception that:

Private Key cannot be used to encrypt

I then checked in my logs that my java on windows machine is using sun.security.rsa security provider and Java on AIX is using com.ibm.crypto.provider

When I further surfed on internet I got to know that IBM does not allow in RSA to encrypt using private key.

Now the problem is that I do have to use private key for encrypton, but it requires to install or somehow embedd new security provider in my AIX Machine ie sun.security.rsa .

Can I do it in my existing code directly? or can I somehow use private key for encryption using ibm package? or any other way around? please help!

I have resolved the issue by using different JCE ie BouncyCastle instead of IBM JCE.
